This study is intended to revaluate old tree, five of the shot of the Natural Monument and 66 shot trees under protection in the city at present. The study covers distribution, management of usage, investigation and research into various matters relating to the situation of old trees in Pusan. Because 60% of the old trees selected for protection is on private land, citizens have difficulty gaining access to them. Also space for growth is impinged on by various urban facilities. Some trees have problems of growth because the land is covered with cement and asphalt. As regards space for old trees, many places have been destroyed due to the lack of protection fences and the failure to establish a guidance board. Only 40% of the space has been set aside for rest. In these places the establishment of rest areas, benches and handy chairs is needed. And there are 20 holy places where people observe religious ceremonies. As for space security necessary for old trees according to trunk width, the minimum trunk width and availale area needed are more than 1:1.5, but less than 30% have the necessary space. The growth of many old trees is threatended because of the small apace for growth. The prescription of the boundary space is divided between inside and outside. This indicates the domain nature and space rank of the old tree. It can be classified into five forms for research purposes. The elements for prescription of critical space outside are connected with the security of space, and the elements relating to inside space portray the conditions for sensitive growth according to the institution and the ground conditions. The open and closed nature of old tree space has some connection with the relationship between usage and the intimacy of the user. Most of the spaces for old trees can't be used or are difficult to gain access to, so it is necessary to secure enough space for them. The 18 places, despite having easy access, are near farmland, hills or forest. So the intimacy factor is low, and the security of space of the old trees is not generally sufficient. Henceforth, it will be necessary to have security of area for old trees as well as maintenance control to protect them. Also the space should be used as a communal and recreation are in the city. It is the time to construct a landscaped area which people can easily approach, a place with a secure entrance where they can play, rest and converse.

호흡기 및 기타생리 : 일반연재 ; Pentacam 장비를 이용한 건강검진 백내장 검사

김승환,권영훈,이명신 대한임상병리사협회 2011 임상생리검사학회 발표자료집 Vol.2011 No.-

배경(Background) 건강검진 안과검사는 기본적으로 시력과 안압측정, 안저촬영으로 이루어져 있다. 본원 건강의학센터에서는 2008년 Pentacam 장비를 도입, 백내장 검사를 신설하였고 일부 프리미엄 건진자와 희망자를 상대로 기본 안과 검사에 추가로 백내장 검사를 실시 하고 있다. 방법(Methods) 2008년 월부터 2011년 7월까지 삼성서울병원 건강의학센터 안과검사를 받은 건진자 145,467명 중 추가로 백내장 검사를 받은 건진자 수를 년도 별, 연령대별로 조사하였고, 백내장 검사를 받은 건진자 중 백내장 유소견 판정을 받은 건진자를 연령대별로 조사하였다. 결과(Results) 백내장 검사를 추가로 희망하는 건진자는 50~60대가 주로 많았고, 백내장 검사를 받은 건진자 13,727명 중 백내장 유소견 판정을 받은 건진자는 2008년 2,809명 중 232명(8%), 2009년 3,541명 중 480명(13%), 2010년 4,564명 중 417명(9%), 2011년 7월 까지 2,813명 중 217명(8%) 이다. 또한 60대 이상 연령대에서 가장 많은 유소견자가 나타났다. 고찰(Discussion) Pentacam 장비를 이용한 건강검진 백내장 검사는 스크리닝 검사로서 백내장의 진행 상황이나 추후 정밀검사, 치료여부 등을 제시 해 줌으로써 의미가 있다. 또한 50세 이상, 눈 관련 과거력이 없거나 특별한 안과 진료를 보지 않는 건진자에게 예방 차원의 검사로 적합하다.

This paper is the study on the activity of citizen participation in the movement of Million Amenity Park's creation which was proposed by citizen participation for large scale's flat park within city. This park was proposed by the Busan Green Plan, commission study in 1999. The location of Park site was finally proposed at Dunchi-do, Bonglim-dong, Gangseo-gu, Busan and neighbor areas. The area of park site is approximately 500ha included the surface area of West-Nakdong River. Citizen's organization for Million Amenity Park which has 3,500 members, was established in 2001 in order to compose Million Amenity Park The development processes of this study were found to have quickening period, germination period, the 1st growing period, and the 2nd growing period, and then the results of this activity was also arranged by the researcher of this study. The movement for this park was found to have a positive activity for participating and understanding all the citizens during 7 years. And then the activities for this park were as follows: every information, fund-raising campaign, organization, purchase of park site, contribution of purchasing park site to Busan city. The results of this study, through the movement of citizen's participation such as this park movement were 1) respectively found to have the settlement in the movement of NGO, 2) the possibility of large scale's park fostering by public and civil partnership, and 3) the model presentation of frontier park in the citizen participation's types which will be able to introduce the development of city.

Comparison of Full Lesion Coverage versus Spot Drug-Eluting Stent Implantation for Coronary Artery Stenoses

Purpose: The aim of this study was to evaluate and compare the long-term clinical outcomes of the spot drug-eluting stent (DES) implantation strategy, which is used to minimize implanted stent length and the number of stents, versus full lesion coveragefor treatment of coronary artery stenoses. Materials and Methods: We evaluated1-year clinical outcomes of 1619 patients with stent implantation for a single coronarylesion. They were divided into two groups: those treated by full lesion coverage (n=1200) and those treated with the spot stenting strategy (n=419). The combined occurrence of 1-year target vessel failure (TVF), including cardiac death, target-vessel related myocardial infarction, or ischemia-driven target-vessel revascularizationwas evaluated. Results: The spot DES implantation group had a shorter stent length (23.14±9.70 mm vs. 25.44±13.24 mm, respectively; p<0.001) and a fewer number of stents (1.09±0.30 vs. 1.16±0.41, respectively; p<0.001), even though the average lesion length was similar to the full lesion coverage group (21.36±10.30 mm vs. 20.58±10.97 mm, respectively; p=0.206). Spot DES implantationwas superior to full DES coverage with respect to 1-year TVF (1.4% vs. 3.3%, p=0.044). Cox proportional hazard model analysis showed that the risk for 1-year TVF was almost 60% lower among patients who received spot DESs compared to those who received full DES coverage after adjustment for other risk factors (HR=0.40, 95% confidence interval=0.17-0.98; p=0.046). Conclusion: Minimizing stent length and the number of stents with overlapping by spot DES implantation may result in reduced rates of 1-year TVF, compared with full DES coverage.

재난 요소 및 재난 패러다임

Disasters are unpredictable and unavoidable. The definition of disaster is a serious disruption of the functioning of society, causing widespread human, material, or environmental losses that exceed the ability of affected society to cope using only its own resources. Disaster medicine is a discipline resulting from combination of emergency medicine and disaster management. The field of disaster medicine involves the study of subject matter from multiple medical disciplines, and disaster medicine presents unique ethical situations not seen in other areas of medicine. Disaster can be classified into two categories, natural disaster and manmade disaster, each type of disaster has its own characteristics. Disaster management has a cycle of 4 activities, preparedness, response, recovery, and prevention/mitigation. Disaster medicine specialists have a role in each part of this cycle. To achieve effective disaster response, the National Disaster Life Support Foundation suggests the DISASTER Paradigm™, which consists of detection, incident command, safety and security, assess hazards, support, triage and treatment, evacuation, and recovery.
